SMF.Bitmap has static functions for image processing. rotate function will help you about your question.

SMF.Bitmap具有用于图像处理的静态函数。旋转功能将帮助您解决您的问题。

Here is a sample code for you:

以下是您的示例代码:

var img = new SMF.UI.Image({
  name: "img",
  image: "smartface.png",
  left: "15%",
  top: "20%",
  width: "70%",
  height: "10%",
  imageFillType: SMF.UI.ImageFillType.ASPECTFIT
});

var btn = new SMF.UI.TextButton({
  name: "btn",
  text: "Rotate!",
  onPressed: function() {
    var myImageUri = "smartface.png";
    var im = new SMF.Bitmap({
      imageUri: myImageUri,
      onSuccess: function(e) {
        im.rotate({
          angle: 90,
          format: SMF.ImageFormat.PNG,
          compressionRate: 0.7,
          onSuccess: function(e) {
            img.image = e.image;
          },
          onError: function(e) {
            alert("Error: " + e.message);
          }
        });
      },
      onError: function(e) {
        alert("Error: " + e.message);
      }
    });
  },
  left: "15%",
  top: "70%",
  width: "70%",
